Cell-Free Full-Duplex Communication -- An Overview
Diluka Galappaththige, Mohammadali Mohammadi, Hien Quoc Ngo +2
Cell-free (CF) architecture and full-duplex (FD) communication are leading candidates for next-generation wireless networks. The CF framework removes cell boundaries in traditional…
Multi-Static Cell-Free Massive MIMO ISAC: Performance Analysis and Power Allocation
Nhan Thanh Nguyen, Tianyu Fang, Hien Quoc Ngo +1
In this work, we consider a cell-free massive multiple-input multiple-output (MIMO) integarted sensing and communications (ISAC) system with maximum-ratio transmission schemes comb…
Distributed Graph Neural Network Design for Sum Ergodic Spectral Efficiency Maximization in Cell-Free Massive MIMO
Nguyen Xuan Tung, Trinh Van Chien, Hien Quoc Ngo +1
This paper proposes a distributed learning-based framework to tackle the sum ergodic rate maximization problem in cell-free massive multiple-input multiple-output (MIMO) systems by…
Performance Analysis and Power Allocation for Massive MIMO ISAC Systems
Nhan Thanh Nguyen, Van-Dinh Nguyen, Hieu V. Nguyen +3
Integrated sensing and communications (ISAC) is envisioned as a key feature in future wireless communications networks. Its integration with massive multiple-input-multiple-output…
Anti-Malicious ISAC Using Proactive Monitoring
Zonghan Wang, Zahra Mobini, Hien Quoc Ngo +1
In this paper, we investigate proactive monitoring to mitigate malicious activities in integrated sensing and communication (ISAC) systems. Our focus is on a scenario where a cell-…
Unicast-Multicast Cell-Free Massive MIMO: Gradient-Based Resource Allocation
Mustafa S. Abbas, Zahra Mobini, Hien Quoc Ngo +1
We consider a cell-free massive multiple-input multiple-output (CF-mMIMO) system with joint unicast and multi-group multicast transmissions. We derive exact closed-form expressions…
